Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultra-low temperature equipment technology, specifically to a modular refrigerator ventilation cover. Background Technology
[0002] During the operation of ultra-low temperature freezers, a large amount of heat dissipation is required to maintain the normal operation of the equipment. Due to the different power energy losses of compressors and other components, the number of heat dissipation holes in the front ventilation cover of the freezer varies depending on the volume of the freezer. Generally, the number of heat dissipation holes increases with the increase of volume. The conventional sheet metal punching method for ultra-low temperature freezers is laser cutting or punching. For mass production, punching is a commonly used method. Punching requires mold making and is suitable for mass production.
[0003] However, if the production volume is small or it is a single-piece production, punching is costly and uneconomical. Although laser cutting is an efficient and precise processing method suitable for sheet metal processing of various materials, laser cutting equipment is expensive and requires a large initial investment. Therefore, using laser cutting or punching in the refrigerator ventilation structure through customized production will increase product costs and production time.
[0004] In summary, considering the need to address the increased product cost, production time, poor repeatability, and poor scalability resulting from using conventional sheet metal punching methods for refrigerator cabinet ventilation structures, and aiming to improve the ease of production and installation of the cabinet ventilation structure, we propose a modular refrigerator ventilation hood.

[0010] Preferably, the ventilation opening is horizontally mounted with slide rails on its upper and lower sides, and the ventilation and heat dissipation plate unit is provided with a bidirectional open slot for sliding insertion into the slide rails;

Detailed Implementation
[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments:
[0031] Example 1
[0032] This embodiment features a modular refrigerator ventilation hood, see attached [reference]. Figures 1-3 As shown in the structure, in order to facilitate quick disassembly and assembly of the ventilation cover at the ventilation opening 101, for some mass-produced products of the same specifications, multiple ventilation and heat dissipation plate units 2 can be installed at the ventilation opening 101.
[0033] In this embodiment, as shown... Figure 1 and Figure 2 As shown, it can be applied to ventilation openings 101 without openings on both sides, and multiple ventilation and heat dissipation plate units 2 can be installed at equal intervals according to horizontal distance. The ventilation and heat dissipation plate units 2 are provided with heat dissipation and ventilation holes 21; for easy and quick disassembly, such as Figure 3 As shown in the structure, a magnetic block 3 is installed on the surface of the ventilation and heat dissipation plate unit 2 that is in contact with the plate body of the fan cover mounting base 1. Most of the current refrigerator cabinets and fan cover mounting base 1 adopt a ferromagnetic structure, which can make the magnetic block 3 attract. In other embodiments, if plastic parts are used in some parts, a ferromagnetic suction plate can be installed on the fan cover mounting base 1 at the position corresponding to the magnetic block 3.
[0034] Example 2
[0035] To further improve installation stability, this implementation example Figure 4 and Figure 5 The structure shown in this embodiment has an open end at the ventilation port 101. A slide rail 5 is installed on the upper and lower sides of the ventilation port 101. The slide rail 5 is horizontally arranged. The upper and lower ends of the ventilation and heat dissipation plate unit 2 are provided with bidirectional open slots 201 for sliding insertion on the slide rail 5, which facilitates the quick and horizontal installation of multiple ventilation and heat dissipation plate units 2.
[0036] To seal the open portion and maintain structural stability, this embodiment provides a one-way open slot 401 at the inner end of the encapsulation cover plate 4 for insertion into the slide rail 5, thus enabling... Figure 4 The insertion state is shown; at the same time, magnetic blocks 3 are installed at the corresponding surfaces of the one-way open slot 401 and the slide rail 5. In order to improve the installation stability, magnetic blocks or magnetic plates are also installed at the connecting surfaces on both sides of the ventilation and heat dissipation plate unit 2. That is, after the sealing cover 4 is inserted and closed, the ventilation and heat dissipation plate unit 2 and the sealing cover 4 will be attracted by the attraction of the magnetic blocks 3. At the same time, the ventilation and heat dissipation plate unit 2 and the ferromagnetic fan cover mounting base plate 1 are also attracted and fixed.
[0037] Example 3
[0038] Considering the inconvenience of insert-type structures in terms of later parts or routine maintenance, this embodiment considers designing a snap-fit structure, so that the guide-mounted structure is exposed, which facilitates routine maintenance or later replacement of partial structures.
[0039] Specifically, this implementation example Figure 6 The structure shown has grooved guide rails 6 horizontally installed on the upper and lower sides of the ventilation opening 101, with a groove in the middle. First guide protrusions 202 are provided on the upper and lower sides of the ventilation and heat dissipation plate unit 2. The protrusions and grooves are slidably engaged to achieve horizontal insertion and limiting. This engaging structure is easy to clean. In order to maintain the stability of the engagement, magnetic blocks 3 are installed on the corresponding surfaces of the first guide protrusion 202 and the second guide protrusion 402 in this embodiment. Magnetic blocks or magnetic plates are also installed on the contact surface of the ventilation and heat dissipation plate unit 2 itself, which can keep the ventilation cover body in an integral structure and magnetically fix it on the ventilation cover mounting base plate 1 to complete the fixation.
[0040] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
